The unknown is the most dangerous! The market is becoming increasingly confused about whether the Bank of Japan will raise interest rates next week. In the past week, with mixed signals from officials and media reports about the Bank of Japan's intention to raise interest rates, traders have become increasingly confused about when the Bank of Japan will raise interest rates. And this scene is obviously reminiscent of the scene before the "Black Monday" in Japanese stocks in August this year - at that time, there was also no "certainty" from the outside world about whether the Bank of Japan would raise interest rates at the end of July meeting, and the final decision of the Bank of Japan to raise interest rates triggered the subsequent liquidation storm of yen arbitrage trading.
